What would happen if airlines and baseball stadiums priced all seats the same instead of using variable pricing

If I had my choice and the seats were priced the same, I would always choose the best possible seat right behind home plate so I could see better, or at the front of the plane so I could exit first and not have to wait after landing. But so would everyone else. It would become a race to see who could get their tickets first.

By making the good seats more expensive than the not as good seats, the airline and ball team can make more money. Also, the person willing to pay more can get a good seat, even if they don't happen to be first in line. This is supply and demand in action. When there is a limited supply of something desirable, like good seats, the seller can charge more and make more money.
